Application filed July 81, 1912. Serial No. 712,490.

To all whom it may concern Be it known that we, ARTHUR I. Hamnr andW'JLLIAM MARoRoFr, citizens of the United States, residing at-Providence and Cranston, respectively, in the county of Providence andState of Rhode Island, have invented certain new and useful Improvementsin Winding-Machines, of which the following is a. specification.

Our invention relates to winding machines for winding yarn and threadinto, cops or bobbins for use in loom shuttles and consists particularlyof improvements in the bunchbuilding mechanism therefor.

The object of our invention is to simplify and improve the structuraldetails of the mechanism shown and described in our pending applicationfor patent, Serial No. 707 ,824, filed July 5, 1912, and to render thedevice adjustable to regulate the length of yarn. wound into the bunchIn the application referred to we have described a device adapted'tooperate in connection with a usual form of winding machine toautomatically control the traverse of the thread-guide at thecommencement of each bobbin so that several layers of yarn are woundwith a relatively short traverse. By this means a short section of yarnis wound on the naked bobbin or tube at the beginning I of thewinding'to form what is technically termed a bunch. The bunch cooperateswith the feeler-mechanism of the loom to actuate the fillin-replenishing device when the yarn in the bobbin becomes nearlyexhausted.

The invention is fully described in the following specification,illustrated by the accompanying drawings, in which Figure 1 is alongitudinal elevation of a winding machine, showing our new deviceapplied thereto, the main frame of the machine being illustrated insection to disclose the mechanism contained therein; Fig. 2, a plan viewof the same; Figs. 3 and 4, enlarged detail views of the stoppingmechanism of the machine Figs. 5, 6, and 7, detail views of parts of thebunch-building device; Figs. 8, 9, 10 and 11, enlarged views of theassembled bunch-building mechanism with the parts shown in thedifi'erent positions which they assume during successive stages of theiroperation.

Our invention is shown as applied to a machine of the same general typeas that described in U. S. Patents Nos. 940,489 and 9 L6,831,'grantedNov. 16, 1909, and Jan. 18, 1910, respectively, to S. W. Vardwell.

The basic machine consists essentially of a rotating winding-spindle Band a reciprocating traverse-bar O, the latter arranged opposite thespindle, and adapted to carry the thread-guide G, which, besides itsmovement with the bar, is fed progressively outward thereon to build thecop in superimposed conical layers. The. winding-spindle B is mounted ina bearing ain the main frame A of the machine and is rotated from themain driving-shaft E by means of skewgears e, e. The traverse-bar Cslides in-a quill-shaped bearing a, which has an extension a extendingthrough a bore in the side of the frame A, and is reciprocated from arocker-arm F mounted. on the continuously-oscillated shaft D. Our newtraversecontrolli..g device" operates directly in connection with thearm F and is arranged to automatically adjust the point of connection ofthetraverse-barC with the arm to vary the operative length of the latterand regl late the length of traverse of the threadguide as more fullyexplained hereinafter.

The traverse-bar C is preferably constructed in two parts Cand C themain portion C sliding in the bearing a, as before explained, and theextension 0 connected thereto at its outer end by a pin-andslot coupling0. The outer end of the extension C is mounted in a bushing c which isswiveled in an outboard bearin j supported on a bracket J extending romthe frame A The coupling 0 allows the inner end of the extension C toswing inward from the plane of the axis tion C of the bar, as shown inFig. 2, while the outer end of the 'bar swings in the swiveled bushingc. This arrangement is the same as that described in U. S. Patent940,489, above referred to, and provides that the contact means carriedon the traversebar, and arranged to feed the thread-guide along thewinding-spindle, shall contact with the first layers of yarn wound on.the bobbin 4v before the base of the cop isbuilt up to its maximumdiameter. The progress1on or contact-mechanism is arranged as of themain porproximately half way around its circumferonce and a spring h issecured to the guideholder 9 with its end bearing on a flange It of thenut h. 'The spring h acts to normally press the nut it into position toengage its threads with the threads 0 on the bar C but the bore of thenut is of suficient diameter to allow its threads to pass over those onthe bar when the nut is pressed in the opposite direction against the.force of the spring. It will be seen that while the machine is operatingthe nut It is engaged with the threads on the barC so that the turningof the wheel H will feed the threadguide along the winding-spindle butby releasing the nut from engagement with the threads on the bar theguide can be slid back to adjust it in position to begin the winding ofa new bobbin.

Mounted on the end of the bar 0 is a former K, so termed because it actsto direct the movement of the contact-wheel H away from thewinding-spindle during the building of the base or heel of the bobbinand therefore determines the form of the latter. The former K has an armis arranged with its edge at an angle to the axis of thewinding-spindle, and by adjusting the arm at different angles the taperof the base of the bobbin can be regulated. Adapted to bear on the edge70' of the arm 70 is a follower-arm 9 extending rearwardly from thethread-guide holder 9. Sliding in a bore at the inner end of the bar Cis a spring-pressed plunger 0, adapted to bear against the inclined facea of the couplingplate 0 and tending to normally hold the bar Cinposition to aline its axis with that of the bar C. The swingingmovement of the bar C is limited by its pin 0 sliding in the slot 0 ofthe plate 0 and when the follower g bears on the rearward end of theformer-arm 70 the end of the bar is held with the pin at the inner endof the slot as shown in Fig. 2. This provides that the contact-wheel Hwill be maintained in close proximity to the surface of the bobbin orcop-tube at the beginning of the winding so that its periphery willcontact with the first layers of yarn wound on the latter at therearwardend of each stroke of the threadguide. The contact of the wheelwith the surface of the yarn, during the rotation of secured in place bythe screw Z oeaeea the winding-spindle,- acts to turn the wheel to feedthe thread-guide outward along the spindle in the manner now well knownto those versed in the art... As the thread-guide feeds outward alongthe traverse-bar C the follower-arm 9 slides along the incline of thearm is and allows the contact-wheel to recede from the axis of thewinding-spindle in accordance with the growth in diameter of thewinding. As the follower 9 reaches the end of the arm is the base of thebobbin or cop attains its maximum diameter'and the bar C assumes aposition in alinement with the bar C. Henceforth the two sections C andQ of the traverse-bar C are reciprocated in the same plane, as onecontinuous bar, and the contact-wheel H engages the bobbin at therearward end of each reciprocation at a pointon the base of its forwardconical end.

In this way the bobbin grows by longitudinal extension, the conicallayers forming a substantially cylindrical body terminating in thetapered delivery end or nose.

The stopping-mechanism of the machine for arresting .the rotation of thewinding spindle and the reciprocation of the threadguide consistsessentially of a rockable bridge-member L which is pivoted on suitablebearings in the frame A and extends across and above the shafts E and D.The inner end of the member L is mounted on a rod 1 secured in the inner'side, of the frame A and the outer end is formed with a socket Z whichreceives the end of an extension L The extension L reaches through abearing in the outer side of the frame A, and secured in a bore at itsend is a rodM held by the setscrew m. The opposite end of the rod Mpasses through a bearing on in the bracket J and is bent down to form ahandle M.

The skew-gear e which is driven from the gear 6 is mounted free to turnon the winding-spindle B and is connected rotatively therewith by meansof a clutch-member N, see Figs. 1 and 2.- The clutch-member N is keyedrotatively with the spindle, but is free to slide thereon to carry' itstapered face n into and out of engagement with the corresponding face aof the gear e. A coiled spring at bearing against a collar 11? tends tonormally maintain the clutch-member N in engagement with the gear 6 sothat the winding-spindle is driven therefrom; and the. clutch-member isreleased from the gear 6 to arrest the rotation of the spindle by meansof a lever 1 The lever Z is preferably formed as a part of thebridge-member L and extends upwardly therefrom with its end adapted toa...

free on the shaftD and connected therewith by a clutch-block O securedon the shaft by a bolt 0. Preferably, the hub f is provided with a keyor spline f adapted to engage a corresponding slot 0 inthe face of theblock 0 and acoiled spring 0 bearing against a collar 0 tends tonormally hold the hub f in engagement with the clutch-block. The hub fis disengaged from the block 0 by means of the bridge-member L which isformed with an overhanging portion Z* having a face Z adapted to engagewith a tapered projection f on the end of the hub f to slide the hubagainst the action of the spring 0 see Fig. A double-ended spring Z, seeFigs. 2 and 4, is secured to the top of the member L with its free endsF, l" reaching down adjacent the sides of the projection f on the hub fof the arm F. prevent excessive rocking movement of the arm F after itsdisengagement from the clutch-block O and serve to hold the arm in suchrelation to the clutch-block as to insure the spline f being engagedwith the slot 0 upon the release of the hub from the member L.

Referring now to Figs. 8, 9, 10 and 11, the arm F is formed with acurved slot f extending from its upper end to a point adjacent its hubf. Connected to the main portion C of the traverse-bar C by a pin a is alink P carrying a stud p at its opposite end adapted to engage the slotf By sliding the stud 72 down in the slot f the operative effect of thearm F may be varied to shorten the extent of traverse imparted to thetraverse-bar C and through the latter to the thread-guide G. At thecommencement of the winding of a bobbin the stud is held at the lowerend of the slot f and will therefore move through an arc of relativelyshort radius when the arm F is oscillated, so that the thread-guide isreciprocated with a relatively short traverse to build the bunch on thebobbin. When the bunch has been built up to the required diameter, or,more properly speaking, when a sufficient length of yarn has been woundinto the bunch, the stud p is shifted to the upper endof the slot f andthe traversebar C will then be reciprocated with the maximum extent oftraverse to wind the full layers which form the main portion of thebobbin.

In our previously filed application, before referred to, the arm F isillustrated as formed in one piece with its hub f. In the presentembodiment of the invention we have preferred to construct the arm Fseparate from its hub so that it may be detached therefrom for thepurpose now explained: It will be seen by reference to the drawings thatall of the parts of the traverse-controlling or bunch-building .deviceare carried The ends of the spring Z act to on the arm F and thereforethe whole mechanism can be removed from the machine by simply taking thearm ofi of its hub. In the previously described arrangement it isnecessary to withdraw the rock-shaft D from the hub f in order to removethe arm F from the machine and this requires taking down a-considerablepart of the mechanism and entails a considerable amount of labor. Thisis particularly true when the machines are arranged in series, as isusual, with a large number of units or heads hav ing one commonrocker-shaft to operate all of their traverse-mechanisms. Sometimes itbecomes necessary to adjust or repair a part of the bunch-buildingmechanism and the most convenient method of doing this is to remove thecomplete device. This is easily accomplished with the presentarrangement of the detachable arm F and, furthermore, another advantageis gained thereby because the mechanism of the ma chine can be madeinterchangeable for performing different varieties of winding.- For theordinary method of winding bobbins without first building up the bunch asimple rocker-arm, similar to that shown in the previous patents to S.W. W'ardwell, Nos. 940,489 and 946,831, of Nov. 16, 1909, and Jan. 18,1910, might be employed and should it be required to adapt the machinefor bunch-winding the plain arm can be removed and the present devicesubstituted therefor. Any suitable method of attaching the arm F mightbe employed, but we have preferred to illustrate it as formed with anarcuate flange f fitted to the periphery of the hub f and secured inplace by the screws S 8 f "I he bunch-building mechanism is arranged asfollows: Pivoted on a screw 1' at the top of the arm F is a sector Rwhich extends downward to a point adjacent the hub f. The sector R ispreferably constructed of sheet-metal and formed with an arcuate slot 7'arranged concentric with the axis of its pivot r. Its lower edge isformed with a series of ratchet teeth 4. The slot- 1" is positioned toregister with the bottom of the slot f of the arm F and is adapted toengage with the stud p, secured in the end of the link P, when the studis in its lowermost position. By moving the sector into the positionshown in Fig. 10 the stud p is held at the bottom of the slot f to adaptthe arm F to reciprocate the traverse-bar C with a relatively shorttraverse; and by swinging the sector R on its pivot in the directionindicated by the arrow 2 the stud p is released so that it can beshifted to the upper end of the arm F, as shown in 'ig. 8, to providefor the maximum throw ,or traverse of the traverse-bar. A spring S, seeFig. 9, preferably formed of wire bent in a helical coil at s, issecured at one end to the top of the arm F by a screw 8'. The lower endof the spring S is bent at right-angles and hooks through one of aseries of holes r r arranged in an arc concentric to the axis of thesector, so that the spring has a tendency to swing the sector in thedirection opposite to that indicated by the arrow 2. The range ofmovement of the sector R'is limited by the end of the spring strikingthe side of the arm F and therefore its extent of movement the holes 1',T for a purpose as fully explained hereinafter. The sector R is n0rmallyrestrained from movement under the action of the spring S by a pawl T,the toe of which engages with the-teeth 1 see Fig. 8. The pawl T ispivoted on a stud I? screwed into the arm F and is formed with an ofisettail-piece or arm t, see also Fig. 3. The end of the arm 25 is roundedoil on one side, as shown most clearly in Fig. 9, and this rounded edgeis adapted to be engaged by the end of the link P as the stud ;0 slidesdown in the slot f Such engagement will swing the pawl T to release itsend from theteeth r and allow the sect-or to swing under the action ofits spring S to engage the slot 1" with the stud 72. Itis to be noted,however, that this engagement can take place only when the hub f of thearm F is slid back from the clutch-block 0 into the position illustratedin Fig. 3. lVhen the machine is operating and the hub f is engaged withthe clutchblock 0 the link P lies against the face of the arm F, asindicated by the dotted lines in Fig. 3, so that normally, the end ofthe link clears the offset arm t. This provides that when the stud 79 isat the bottom of the slot f during the first stages of the winding. theend of the link will ride past and in back of the arm T withoutreleasing the pawl T when the arm F oscillates.

The pawl T is normally maintained in engag r nent with the teeth 7 onthe sector It by a spring U fastened to a standard V mounted on theflang-- f of the arm F. The standard V is preferably constructed ofsheet-metal and formed with a foot 41 secured to the flange f by a screw0. The spring U is constructed of flat, spring-metal split into twobranches at and u, as shown in Fig. 7, and secured in place by a screw11. extending through its upper end. The end of the branch/u, engagesthe offset shoulder of the arm t of the pawl T, while the branch uengages another element of the mechanism later described.

The sector R is swung in the direction indicated by the arrow 2, torelease the stud p, by the intermittent action of the pawl W actuatedfrom the oscillating motion of the arm F, see Figs. Sand 11. The pawl VVis pivoted at the lower end of an elbow-shaped member 4, shown in detailin Fig. 6, which,

in turn, is pivotally mounted on the standard V by means of the screw 5.The member 4 is preferably constructed of sheet-metal and the extremityof its lower arm 6 is bent outward to form a. shoulder or abutment 7see.

Figs. 5 and 6, which serves as a stop to engage one side of thestandardV. The lower end of the branch u of the-spring U engages theouter side of the abutment 7 to normally maintain it against the side ofthe standard V with the member 4.- in the position illustrated in Fig.8.

The pawl W is pivoted on a stud 'w. screwed into the member 4 as shownmore particularly in Fig. 5. The toe w of the pawl is ofis'et from itsmain portion and lies directly under the teeth 7' on the sector R withwhich it is adapted to engage. Bent forward from the main portion of thepawl is a finger 10 which overlaps the edge of the member 4 and isadapted to engage therewith to limit the downward movement of the toe'w'. A wire spring 8 is bent around the stud 10 with its end extendingup over the back of the finger Q0 and, preferably, a groove 103 isformed on the edge of the finger to retain the spring in place.

The spring 8 is held from turning on the stud w by a nut 10* set upagainst a washer 10 which binds the spring against the member 4.Extending rearwardly from the pawl V is an arm 10 having its end bentinward at w", as shown in Fig. 5. The spring 8 tends to normallymaintain the pawl in the position illustrated in Fig. f3 with its toe wjust clear of the teeth 7 of the sector R. With the pawl W in thisposition the end of the arm 'w'is raised to adapt it to be engaged bythe lower edge of the link P whenthe arm F is rocked into its rearwardposition as illustrated in Fig. 11. This engagement takes place onlywhen the stud p is at the bottom of the slot f in the arm F, but duringthis time the arm '10 will be engaged at each rearward oscillation ofthe arm F. The engagement of the link P with the arm w rocks the pawl \Vto carry its toe w into engagement with the teeth 1 and the movement ofthe pawl is then continned forward to swing the member 4 on its pivot sothat the sector R is swun in the direction indicated by the arrow 5 toshift it one tooth on the holding pawl T, as more fully explainedhereinafter.

Referring to Fig. 8, the arm F has a transverse counterbore at f with asmaller bore f at its end, reaching into the slot f Mounted in the boref is a plunger 9 formed with a head 10 which slides in the counterbore7. A, spring 11, retained in the counter-bore by a screw 12, engages thehead 10 to force the end of the plunger into the slot i as shown moreplainly in Fig. 9. Referring again to Fig. 8, the end of the upper endof the slot f and the pressure 0 the spring 11 tends to hold the plungerin 7 position to retain the stud at the end of ,the

slot against the normal thruston the link JP.

Secured at one end to the top of the standard V is a flat,sheet-metalspring 13 held in place by the screw 14. The spring 13 isbent downward in a U-shaped 1100 with its free end 15 reaching up adacent t e end of the traverse-bar C. Thespring 13 is adapted to engagethe end of the bar .Cat each forward oscillation of the arm F and whenthe stud p is released from the sector B it acts to push the bar-forwardto carry the stud to the upper end of the slot f as more fully explainedhereinafter.

Referring to Fig. 3, it will be noted that the overhanging portion Z ofthe bridgemember L, which engages the projection f on the rear end ofthe hub f, has a pin .1 extending outward over the projection. The pin Zis adapted to engage with a depression or groove f in the top of theprojection f when the arm F is rocked into its forward position, seeFig. 4. The engagement of the pin Z with the groove f takes place onlywhen the arm F is disconnected from the clutch-block O, as shown in Fig.3. That is to say, during the operation of the machine the bridge-memberL is in such position that its, overhanging portion l is raised free ofthe projection f on the hub f, as shown by dotted lines in Fig. 3, andconsequently the pin Z is out of range of the groove f in the top of theprojection. When the bridge-member L is rocked to stop .the machine itsoverhanging portion 8* is brought down into engagement with the bevelededge of the projection F, as shown by full lines in Figs. 3 and 4, andpreviously described, and the pin .Z is carried into position to engagethe groove f. The object of this engagement is to hold the arm F at theforward end of its stroke so that the traverse-controlling mechanism maybe set in its initial posit-ion to start the winding of the bunch, asmore fully described hereinafter. It is also to benoted that it is notnecessary for the arm F to be in its forward position when the portionZ" of the member'L rocks downward inorder to effect thisengagement ofthe pin Z with the groove f Should the movement of the arm F be arrestedin any position other than that at the forward end of its stroke theprojection f can be swung over under the in Z by simplyn rocking the armF forward Such movement .of' the arm is efiected manually by pulling thetraverse-rod C outward through its bearing in the frame A. It will beobserved from tion f? is roundedofi at f to adapt the pin Z to ride uponto the .topof the projection and the inherent sprin tendency of thepin causes it to .spr ng own into the groove f when the latter comesinto alinement with t pin- The operation of the whole machine is asfollowsi Referring first to Figs. 1 and 2, we have here shown a woodenbobbin a; of usual form applied ,to the winding-spindle B, but otherfqrmsof holders for the yarn, such as paper copetubes, for instance,might be empl yed With equal effect. Figs. 1 and 2 illustrate themachine at the beginning of the Winding and we have shown the traverserocker-arm F at the forward end of its throw. It is obvious, however,that the machine will ,not always stop with the arm F in this position,nor is it necessary, because, before starting the winding the operatormust set the bunch-building mechanism and he is instructed to performthe following operations: The first step takenis to pull thetraverse-bar .C outward in the direction indicated by the arrow 3, seeFig. l, and if thearm F is in any other position than at the forward endof its stroke it will be rocked forward until the pin Z engages thegroove f in the projection f of the hub f. This engagement of the pinand groove locks the arm F in its forward position, as shown in Figs. 1and 4. The operator now pushes the traverse-bar C backward in theopposite direction and, the arm F being held from movement, the stud pon the link -P is forced down totheibottom of the slot f During the timethe machine is operating to wind with the full traverseof the threadguide the sector It remains in the position illustrated in Fig. 8, beingheld against the action of the spring S by the ,pawl T. It will ,benoted that the upper edgeof the slot .7" of the sector R is rounded offand forms a point r projecting from the forwardedge of ,the. upper partof the sector.

with the -.sector R in the position illustrated in Fig. -.8 the point orabutment r projects part way ,across the slot f of the arm F.

Now, .as ,the stud p is pushed down in the slot f it will .ride up overthe rounded edge of theabutment 7' and force the sector back into theposition shown in Fig. 9. It mustbe noted, however, .that this movement.of the sector B inder-action of the stud pldoes not carry it back farenough for the'pawl '1 to engage another tooth on its lower edge, butonly releases the/pawl from the tooth first engaged. This provides thatas the stud p is pushed still farther down in the slot-7 and ;the endofthe link P comes into contact with the arm t of the pawl T the latterwill be free to be moved'by the link to its toe outof, range of theteeth T n othe wa d h PaWlT s fir t rel sed some binding engagementwarthe tooth I r bythe sli ht rearward movement of the secto'rR so at itjisfree to be operated by the linkP which enga s its arm 26'. The

awl T will'then be he d free of the teeth 8 the link P while the stud ppassesthe a utment'rand the sector R will be swung ferent holes, asbefore describe and in this way the extent of movement required torelease the stud from the sector can be varied to regulate the/number ofreciprocations of the t read-guide with the short traverse, as

- furtherexplained hereinafter. In the draw-' ings we-have shown thespring S adjusted in the last hole, soas to provide or a maximummovement of the sector-R before the stud p is released, and consequentlya relatively large number of reciprocations of the guide will take placewith the short traverse and hence a comparatively long length of yarnwill be wound into the bunch. The parts as last described are now theposition illustrated in Fig. 10 and the bunch-building mechanism is setready to wind the first layers of thebobbin with a short traverse. Thethread-guide G is next adjusted in its rearward osition on thetraverse-bar U, as shown in Fig. 2, and the yarn 3 is threaded throughwith itsend secured to the bobbinm.

The operation of the machine is started by turning the handle M whichoperates the bridge-member L to release its lever Z from theclutch-member N, it being understood that the member L is withheld fromaction by suitable detents, not here shown. As the clutch-member N isreleased itis carried into engagement with the gear a, through theaction of the spring n, and the rotation of the gear imparts rotation tothe winding-spindle B. Concurrently with the release of theclutch-member N, the projection 7' is also released from engagement withthe member Land the hub f of the arm F slides into position to engagethe clutch-block O, under the influence of the spring 0 As the sloto'--roeks into alinement with the spline-f on the hub f the two areengaged and in this manner the arm F is connected to the rocker-shaft Dand'is oscillated thereby. As the hub f slides into engagement with theclutch-block O the arm at moves laterally with it and rides oif the endof the link P which comes up against the face of the arm F, assuming thepos1- tion illustrated by dotted lines in Fig. 3, and previouslydescribed. This action releases the pawl T and allows itsv toe toenmamas gage the teeth r on the sector R, under in-' ward position,illustrated in Fi 11, the

lower edge of the link P strikes t e end of the arm to of the pawl W androcks the pawl to engage its toe with the teeth 7* on the sector B. Thisengagement of the link P with the arm w continues throughout asufiicient portion of the stroke of the arm F to cause the member 4 tobe swung back to move the sector B one tooth on the holding pawl T. Now,as the arm F swings back in the opposite direction the spring U acts toreturn the member 4 into position for the pawl W to engage the nexttooth 1' backward movement of the member 4 being limited by the stop 7.In this way the sector It is shifted one tooth at each backwardoscillation of the arm F until the stud p is released from the slot 1".It will be understood that as the sector It is shifted each time theholding pawl T prevents it from returning, under action of its spring S,and it is to be noted that the movement of the pawl W and the member tcarries the sector slightly beyond the extent necessary for the pawl Tto engage the next tooth. Referring to Fig. 9, this is provided in orderthat after the abutment T has passed out of range of shown in Fig. 8with the abutment slightly overlapping the slot i The purpose of thisprojection of the abutment 1" across the slot f has been previouslydescribed in connection with the explanation of the preliminary thissetting of the mechanism; the object being to provide for the releaseofthe toe of the holding pawl T from the teeth 1' so that the pawl maybe free to be moved by the end of the link P.

After the sector R is moved to the position shown in Fig. 9 the stud pis free to slide up the slot f and this is efi'ected by the pressure ofthe spring 13 which engages the .fore described.

Referring to Fig. 2, it will be seen that while the stud p is at thebottom of the slot the arm F will act to reciprocate the thread-guidewith a comparatively short traverse to form the bunch the stud pat thethe yarn-is laid wit a traverse substantially. twice .as long asillustrated by the layer 3 The number of layers or traverses of the yarnin the bunch 3 is determined by the number of oscillations required tomove the sector R into position to release the stud p and'this can bevaried by adjusting the spring S. As here illustrated the spring S isshown in the last hole 7' the holes correspond in number to the teeth 1'twelve strokes of the arm F must take place before the stud pis shifted.When the spring S is moved to the hole nearest the arm F only oneoscillation of the arm F is required to release the stud p, but usuallythe mechanism is not set as close as this. Our new device provides for awide range of adjustment, however, and can be set to wind either a veryshort length of yarn in the bunch or a considerable length if required.In this waythe yardage of the bunch can be 1 controlled accurately andpositively for each bobbin. This is a most important feature andprovides against waste which would result if the bunchbuilding mechanismwere arranged to be controlled manually; The yardage required in thebunch depends upon the width of cloth to be woven from the yarn on thebobbin and it is very necessary to have a suflicient length so that comeentirely exhausted in its last throw across the loom before a new bobbinis supplied. For this reason it has been the custom to provideconsiderable more than enough yardage in the bunch to prevent miss-picksand where the human factor is an element in determining, the properyardage it is inevitable that considerable waste.

while with With our new device the mechanism can be set by a competentoverseer to provide the proper yardage in the bunch, and all the bobbinswill then be wound uniformly according to requirements. Furthermore, inour present embodiment of the invention the bunch-building device can beapplied to machines now in use with but slight alteration of-theirmechanism and such machines are rendered interchangeable for othermethods of winding.

It is obvious that our new device might be applied to machines ofdifferent design from that here shown and described, or adapted forother arrangements of winding mechanism.
